Suppose that Henry went to the store to buy his sister a birthday present and started with $13.73. While shopping he became hungry and grabbed a pretzel for $2.34. Then he saw a toy that he really wanted, so he bought it for $6.12. Finally he found a gift his sister would love, but it was $10. How much does Henry need to save to buy the gift?

Henry needs to save $4.73

$13.73 - $2.34 =$11.39

$11.39 - $6.12 = 5.27

$10 - $5.27 = $4.73
